My RV guy needs to build an electrical adapter(6pin round to 5pin flat) to connect a MC tandem trailer. Need a techy to provide a "schematic"(wire colors port to starboard on the MC 5pin flat) with corresponding function of each wire. Who knowz?

white-ground
green-right turn/brake
yellow-left turn/brake
brown-running lights
and what ever is left will be the back up. I think it's blue most of the time.

I don't have those in order...that's just how all trailers are supose to be.

Being a vet, can you suggest anything for TeamTalk leg humpers other than a (((((shock collar)))))????????

why don't you just change the connector on the trailer to fit your truck...or splice another connector on it so you have both?

Lose the 6 round, install a 7 round, and buy the correct adapter. IMO

What uses a 6 round plug anyway??

Horse trailers. That's why I have one at least.

The blue wire is the only one added to the MC harness. Have him connect a lead to the brake lights for the blue lead. That's the only difference and it shouldn't be that hard. The rest is standard configuration.
